An effective environmental approach to SUD prevention includes which of the following?

The effective environmental approach to substance use disorder (SUD) prevention encompasses strategies that impact the broader community and structural factors rather than focusing solely on individual behavior. Providing store clerk training to better check IDs addresses a crucial environmental factor related to the availability and accessibility of substances, particularly for underage individuals. By ensuring that clerks are trained to properly verify ages and prevent sales to minors, this strategy directly impacts the community's ability to limit youth access to alcohol and other substances.

Training store clerks is a proactive approach that not only prevents immediate substance access but also fosters a cultural shift towards responsible retailing within the community. It creates a more supportive environment for prevention efforts and can be part of a comprehensive strategy that includes policy enforcement and compliance checks.

Other options focusing on specific skill-building courses or curricula, while valuable educational strategies, primarily influence the individual level rather than altering environmental conditions or structural barriers.
